There are a lot of opinions flying around about COVID-19. So, it's hard to know just how freaked out we should be about how far it will spread and the number of people it will affect.

But that doesn't mean you should stop washing your hands.
In the video below, Sanderson uses his numerical skills to show what the disease's "exponential growth" really means from a pure numerical perspective.
